A wide range of filters are offered by mac marketing corporation through the working of metal wire, whether in stainless steel, iron, bronze, monel or brass, when pressed in special dies, results in filters in a wide variety of shapes. These filters find their applications in the main function of filtering liquids may include damping discharge noise emitted by pneumatic equipment; acting as flame cutters; absorbing gas and liquid spills; protecting measuring equipment; and separating two liquids with different surface tension. To suit the highly specialised engineering market, there are various types and configuration of pneumatic fittings. These filters reach a very high mechanical resistance. These filters ensure guaranted long life, after undergoing diffusion even under high pressure. The filters which are offered can be applied wherever it is necessary to have. To achieve the results, filters in stainless steel [aisi 304-316] are used, in the other cases, sintered filters are available in bronze, brass and/or other metals. Various silencer models are available ranging from 1/8" to 1" having pressure ranging from 1 bar to 6 bars, to solve all types of requirements, including noise reduction level, to less than 100 decibels.
